Data Consistency for Cooperative Caching in Mobile Environments

In mobile ad hoc networks (MANETs) has autonomous nodes that can change location itself on the fly. Nodes move spontaneously and node failures are common, which pointers to common network partitions. When a network is partitioned one part of mobile nodes cant access data hosted by nodes in another part of partition, so the performance of data access is reduced. To manage this kind of problem, we propose data replication technique. Existing data replication technique can deal with any one of following: reducing the query delay, improving the data accessibility and data collision. We propose a mechanism called data replication technique to deal smooth trade-offs between data availability, data collision and query delay. Simulation result shows that proposed replication technique can achieve both query delay and data accessibility with higher performance.
